Who makes an affordable wheel like this?

Car is a 1974 swinger stock length 8 1/4 I am re-doing a set of 14" Magnum 500s right now, but not sure if I am going to stick with them, would like to move up to a 15" or bigger. Ordering 14" radials are getting so expensive....

So I am looking for an affordable set of rims that look like these, http://www.bossmotorsports.com/custom_chrome_wheels.cfm?id=1920&cat=467 Should I just keep looking for a set of the mustang pony rims that look like these or does someone else make a set that's affordably priced? I want black or silver/grey anything but chrome.

I say affordable, but I actually don't know what a new rim should cost seeing as I have never purchased a new wheel.
